摘要
环签名提供了匿名发布信息的有效方法,现有环签名方案存在不可追踪签名者真实身份的问题。基于身份密码体制和双线性对技术,提出了一种环签名方案,方案除了满足无条件匿名性和不可伪造性,还满足可撤销匿名性,必要时由PKG(Private Key Generator)充当仲裁验证者,达到定位真实签名者的目的。
Ring signature provides effectual ways to distribute information anonymously,lots of ring signature schemes have the problem that they are not able to trace the identity of true signer.Based on identity public key cryptosystem and the technology of bilinear pairing,a class of ring signature scheme is proposed,the scheme satisfies besides unconditional anonymity and unforgeability,it also meets the revocable anonymity,arbitral verifier PKG can locate the identity of the true signer.
